back at trying to find the front drivers side airbag/system leak.

put it up on jack stands and hooked up my test pressure gauge set.  dont pay attention to the label i wrote on the test jig.  the right side is going to the line that feeds the ping tank that feeds the airbag.  the other side goes to the six pack.

i pressurized it up using the air in the coach (shop air) to 100psi both sides.  then closed the ball valve between the two sides to isolate each side.  the side going to the six pack stayed steady at 100psi.  the side headed towards the airbag went down 20 psi to 80 in 24 hours.  

next step is the start trying to isolate the leak. once again.....

all there is is the line from the six pack to the ping tank.  the fittings on the ping tank...and the line to the airbag.  the airbag is new.

A little gem I found on mine.Raise coach as high as possible with bags.Supply guage would drop 5 psi in 16 hours.Level coach lower so I was not jumping off a cliff when exiting the coach and supply would drop 20 psi in 5 minutes.Ok time to play with bubbles.valve that release genny slide pooring out air. Put gate valve in front of it( too cheap to replace original)That should be it.Nope, 20 psi drop in 6 minutes.next up air fitting (push type ) going to curb side air waste valve.Replaced with compression fitting.No improvement.Raise coach back up high.supply guage drop 5 psi 22 hours.Drop it back down gushing air again.can not get under it to look when that low.Jack up put blocks under wheels lower back down.push connector on six pack was leaking bad.something was putting fitting in a bind when coach was low making it leak.3/8 to 1/8 fitting if memory serves.replaced fitting with a new push fitting did not have correct size in brass.All is well.Nope, there is another one just like it that was not leaking until I after I fixed the first one. waiting on brass fittings for mo better repair.Currently aux compressor cycles every 6 hours. I know it can be better but after 2 days of frustration cussing and kicking the dog I am taking a break.good luck tom.
